DESCRIPTION AND OPERATION (Continued)
WASHER PUMP
The washer pumps and motors are mounted on the
right end of the upper radiator shroud near the bot-
tom of the washer reservoir. A barbed nipple on the
pump housing passes through a rubber grommet seal
installed in a hole near the bottom of the reservoir.
The washer pump is retained by an interference fit
between the barbed pump nipple and the grommet
seal, which is a light press fit.
A permanently lubricated and sealed motor is cou-
pled to a rotor-type pump. Washer fluid is gravity-fed
from the reservoir to the pump. When the motor is
energized, the pump pressurizes the washer fluid
and forces it through the plumbing to the nozzles.
The washer pump and motor units cannot be
repaired. If faulty, the entire washer pump and
motor unit must be replaced.
WASHER FLUID LEVEL SENSOR
The standard washer fluid level sensor is mounted
on the right outboard end of the upper radiator
shroud near the front of the windshield washer res-
ervoir. A barbed nipple on the sensor is press-fit into
a rubber grommet seal installed in a hole in the side
of the reservoir.
When the fluid level in the reservoir falls below
the pivoting float on the sensor, the float changes
position and closes the internal switch contacts of the
sensor. Refer to Low Washer Fluid Warning Lamp in
the Diagnosis and Testing section of Group 8E -
Instrument Panel Systems for diagnosis of the low
washer fluid warning lamp and circuit, including the
sensor.
The washer fluid level sensor cannot be repaired. If
faulty or damaged, the sensor unit must be replaced.
WASHER NOZZLE AND PLUMBING
FRONT
Pressurized washer fluid is fed through a single
hose, attached to a barbed nipple on the washer
pump. The hose is routed from the washer reservoir
to the dash panel along the top of the right front
wheelhouse inner panel. At the dash panel, the hose
passes through a grommet inserted in a hole in the
cowl plenum panel to an in-line fitting located in the
cowl plenum area, beneath the cowl plenum cover/
grille panel.
A hose from the in-line fitting in the cowl plenum
is routed through clips molded into the underside of
the cowl plenum cover/grille panel to a wye fitting
near the passenger side washer nozzle. Hoses from
the wye fitting are routed to the two washer nozzles,
which are snap-fit into openings in the cowl plenum
cover/grille panel.
WIPER AND WASHER SYSTEMS
The wye fitting includes an integral check valve to
prevent the washer fluid from draining from the noz-
zles back to the reservoir or from leaking out of the
nozzles after washer operation is complete. The two
fluidic washer nozzles are not adjustable. The nozzles
and hose fittings cannot be repaired and, if faulty or
damaged, they must be replaced.
REAR
Pressurized washer fluid is fed through a single
hose, attached to a barbed nipple on the rear window
washer pump. The hose is routed from the washer
reservoir to the dash panel along the top of the right
front wheelhouse inner panel. At the dash panel, the
hose passes through a grommet in the dash panel
into the passenger compartment. Inside the passen-
ger compartment the hose is routed down the right
cowl side inner panel to the sill, then along the sill to
the right quarter inner panel. The hose is routed
along the quarter inner panel and up the right lift-
gate opening pillar to the liftgate opening header.
Located near the top of the supply hose routing,
beneath the right liftgate opening pillar trim, the
hose connects to a check valve. The check valve pre-
vents washer fluid drain-back or siphoning from
occurring. From the check valve, another single hose
is routed to the liftgate opening header panel. There
the hose passes through a grommet out of the liftgate
opening header and through another grommet into
the top of the liftgate inner panel. Within the lift-
gate, the hose is connected to a nipple that protrudes
from the fluidic washer nozzle, which is snap-fit into
a keyed hole in the top of the liftgate outer panel.
The rear window
adjusted. The nozzle, check valve, and hose fittings
cannot be repaired and, if faulty or damaged, they
must be replaced.
